The crossheads carry asetvof form inking and distributing rollers 4 and ductor 4a (see Fig. 3) beside cylinder 1a to; supply ink to the forms on bed 1, and a similar setof inking rollers 5 and ductor 5a beside cylinder 2a to supply ink to the forms on bed 2. Duc tor 4a takesink from an. ink fountain 6 at the outer end of the press, and ductor Batakesink from'asimilar fountain 60, above fountain 6, the ductors taking inkfrom the fountain rolls when the'cylinders'are at the end of their out ward rnovement The web is fed forward over the beds intermediate the taking of impressions as the afores'aid,Duplex press.

-z'lhus far the partsare all arranged and opelated-substantially8 in theordinary Dupleig flatbed web perfecting press", such for example s h w in liechm n Q- 8. .142 h press so far described is capacitated to print a four-pageewide webin one color on eachIbed producingsa perfected eight page paper inone color. 1 p i i r ii {110 enable the; press :to print a smaller paper in two; colors li provide an auxiliary or'third inlgfountain 6b preferably rn'ounted above fountain fia and supported on standards 60 attached to the pre ss,,frame, with its fountain roll. in p sitionztoli er QW wte y the duster 511 n the, latter; is-iproperly adjusted as hereinafter described. The ductor 5a is mounted in yertis ll adju t b s ve 5w s Fig! 1 each proyided with a substantially vertical slot 512 transfixed bya bolt tapped into the" side of the icrosshead and having a finger 5d transfixed basnaeqiu'sti bqlt es es'm s er d of the crosshead, and the support has a projection 5 engaged by an adjusting bolt 59 tapped through a stud 5h on the crosshead.

By loosening bolt 5c and adjusting bolts 5g and 5c the ductor 5a can be adjusted approximately vertically on the crosshead so that in lower position the ductor will take ink from the roll of fountain Go as indicated in dotted lines in Fig. 3, and when adjusted to upper positionwill take ink from the roll of fountain 6b and also retain contact with distributing roll 5. For convenience of construction the fountain '61) has an undershot roll, while fountains 6- and- So have overshot rolls. This is to lessen; the vertical adjustment of ductor 5a. Inits lower position it takes ink on its underside from the upperside of the roll of fountain 6a and in its upper position it takes ink on its' upper" side from the underside of the roll of fountain 6b. Y

The fountains 6 and 6a customarily contain black ink and when a full width (4 pages wide) web is used the ink is supplied from fountains 6, 6a and an eight page paper is produced. When it is desired to print in two colors,'for instance black on lower bed and redon: therupper bed,

a two page wide web is used and-only four page papers are produced. The full width web cannot be printed in two colors, as when color is used the narrow web has to pass through'the printing mechanism twice, once for each color, and is printed in only one color oneachbed, as sayred on upper bed and black on lower bed. u When printinga narrow web in two colors, th

color, say, red, would be placed in fountain 6b.

" The web is then led from a half width (two pages wide) web roll at W, and through the press on say the right hand side thereof, in the manner above described as far as the web guide 0. In this passage pages two and three are printed in black on one side of the web by cylinder la and bed 1, and pages one and four are printed in red on the opposite side of the web by cylinder 2a and bed 2.

Thus far the lead of the web is identicalwith that of the four page wide web-in regular one color printing, the only difference being that the web is two pages wideinstead of four. I

In order to then printblack on pages '1 and 4 and red on pages 2 and 3, it is necessary to pass the web through the printing mechanism'again,

and, as the black and red colors are to be printed from the same fountains and by same bed'and cylinder "as before, it is necessary to deflect the web., This is done by leadingthe narrow web from roll over the angle 'barp'around guide ate and over the other'angle bar r, to guide roller s, which displaces the web'to the left hand side of thepress, but instead of passing-thence to roller a; the web is lead from rollstocompensator guide rolls 1), thence over guidesu, v, to'guide c, and'from this guide 0 on through the press to guide roll 0 the path of the web is identical with the first passage except it is laterally-displaced. Pages 2 and 3 having been'previously printed in black on the lowertype bed areagain printed iliary ink fountain "rolL'r i v the width of the paper, in other words a 2 or 4 page paper. Now, if it is desired to print a 4 page paper, black and red on both sides of the web, black ink is used in the bottom fountain, (the fountain on the bottom deck) and red ink in the auxiliary fountain,.and ,themain or lower fountain of the top deck will not'be used; in other words the upper black fountain can remain full of black ink which may have been used the day before and may be used the day after after the color run is wanted. As the paper passes from the supply roll to the bottom deck pages 2 and 3 will be printed in black; as it continues through the upper deck pages 1 and 4 will be printed in reclpthe paper then goes to the angle bars and guide rolls which deflect the paper and guide it into the press again parallel with the first run and as it passes through the press the second time pages 1 and 4 will have black ink printed on them on the lower deck and pages 2 and 3 will be printed in red ink on the upper deck thus giving red and blackonall pages of a four page paper, suitable forms or printing surfaces being placed on the beds fromwhich the proper impressions H can be taken. v I v 100 The usual call for color printing in this class ofwork is to put a red scare head orsuh title on the title page and embellish the: advertising pages with red ink or sometimesother colors.

The lead of the web is indicated clearly in Fig. 2, the portion offthe web in its'second passage through the press lying parallel: with the portion of the web in taking its firstpassage through the press. After the web has reached the guide roll 0 the second'time it is taken over guide roll w and led directly'to the drag roll at on top of the former and then down the former 8 to the folder, where the product is folded and delivered in the usual manner. This combination of web lead and auxiliary fountain will print four pages in black andcolor. If for any reason this sequence of printing is not wanted, the fountains may be divided or blocked, using color and black in either orboth fountains as described in the Bechman patents above mentioned.

If desired a press could be built or provided with supplemental color fountain like fountain 6b above the lower fountain 6 and make ductor 4a adjustable like ductor 5a,-so that color could 125 be printedon either the upper or lower bed.
